Migratory Bird Tracking

There is a new online mapping tool that allows you to view bird migration journeys around the world or right in your zip code.

'Migratory birds are these little globetrotters,' said Jill Deppe, the senior director of the migratory bird initiative at the National Audubon Society.

A new online atlas of bird migration, published on Thursday, draws from an unprecedented number of scientific and community data sources to illustrate the routes of about 450 bird species in the Americas, including the warblers.

The Bird Migration Explorer mapping tool, available free to the public, is an ongoing collaboration between 11 groups that collect and analyze data on bird movements, including the Cornell Lab of Ornithology, Smithsonian Migratory Bird Center, the U.S. Geological Survey, Georgetown University, Colorado State University and the National Audubon Society.

For the first time, the site will bring together online data from hundreds of scientific studies that use GPS tags to track bird movements, as well as more than 100 years of bird-banding data collected by USGS, community science observations entered into Cornell’s eBird platform, genomic analysis of feathers to pinpoint bird origins, and other data.

The site allows a user to enter a species – for instance, osprey (featured image) – and watch movements over the course of a year. For example, data from 378 tracked ospreys show up as yellow dots that move between coastal North America and South America as a calendar bar scrolls through the months of the year.

As new tracking data becomes available, the site will continue to expand. Melanie Smith, program director for the site, said the next phase of expansion will add more data about seabirds.
